Imagine you run a business and you need different tools for different tasks. For example, you wouldn't use a heavy-duty truck for a quick trip to the grocery store or a sports car to haul construction materials. Similarly, when companies move their data to the cloud, they often choose one main tool to store and process all their data, like putting everything in one big warehouse or lake. However, this warehouse or lake is very expensive to use for all kinds of tasks, especially for small or less important ones. Gartner (2023) notes that most organisations overspend in the cloud because they default to a single, high-cost compute layer for all workloads, even though most tasks do not require it.
